Abstract
Abstract
Cortriatriatum Dexter (CTD) is an uncommon congenital cardiac anomaly defined by the presence of abnormal septation within the right atrium due to incomplete reabsorption of the right venous valve. While Cor triatriatum with obstructive membranous is often found in early infancy, the non–obstructive forme (“forme fruste”, ff–CTD) usually remain asymptomatic until late adulthood. Non–obstructive forms, in fact, generally have a modest clinical impact, but in some clinical situations, they may represent a significant obstacle. CTD and ff–CTD are commonly associated with other congenital heart anomalies, e.g. atrial septal defects (ASDs), and a few cases of extreme difficulties in percutaneous procedures like ASD or patent foramen ovale (PFO) closure have been described.
We present a case of a 51–year–old male patient with a recent diagnosis of paradoxical cardioembolic stoke that during the procedure of percutaneous PFO closure, ff–CTD was detected. Multifenestrated Amplatzer septal occluder 18 mm device was successfully deployed under TEE monitoring, confirming optimal positioning and no distortion of the device, particularly of the right disk.
Conclusion
cc–CTD is generally a benign condition but may represent a challenge and should be searched prior to percutaneous heart procedures.

Abstract
Backgsround: Infective endocarditis (IE) of prosthetic valves is a dire complication of cardiac valve replacement surgery and is associated with high rates of morbidity and mortality. Case Summary: A 72-year-old woman with multiple comorbidities underwent surgical replacement of the aortic valve with a mechanical prosthetic valve after recurrent IE. After 10 years, IE recurred and the mechanical valve was surgically replaced with a bioprosthetic valve. Ten years later, severe heart failure developed due to severe paravalvular leak (PVL) caused by an aortic annulus abscess complicated by a paravalvular pseudoaneurysm fistula (PPF). The patient was deemed at prohibitive surgical risk and a catheter-based PVL closure procedure was planned. However, the interventional procedure was delayed several months due to the Covid-19 pandemic with progressive heart failure worsening. Despite an acute satisfactory result of the PPF transcatheter closure and a significant clinical improvement, the patient died 10 months later due to multiorgan failure. It is likely that this was due, at least in part, to the long treatment delay caused by the unprecedented strain on the healthcare system. Discussion: In patients at high surgical risk, early diagnosis and prompt interventional treatment of severe PVL are crucial for improving expectancy and quality of life. However, the recent outbreak of COVID-19 caused deferral of elective and semi-elective structural heart disease procedures (SHD) as in our case. Thus, a proactive and vigilant stance on managing SHD should be a priority even in the context of the COVID-19 pandemic.

Abstract
BACKGROUND Myocardial scar appears brighter compared with normal myocardium on echocardiography because of differences in tissue characteristics. The aim of this study was to test how different ultrasound pulse characteristics affect the brightness contrast (i.e., contrast ratio [CR]) between tissues of different acoustic properties, as well as the accuracy of assessing tissue volume. METHODS An experimental in vitro "scar" model was created using overheated and raw pieces of commercially available bovine muscle. Two-dimensional and three-dimensional ultrasound scanning of the model was performed using combinations of ultrasound pulse characteristics: ultrasound frequency, harmonics, pulse amplitude, steady pulse (SP) emission, power modulation (PM), and pulse inversion modalities. RESULTS On both two-dimensional and three-dimensional imaging, the CR between the "scar" and its adjacent tissue was higher when PM was used. PM, as well as SP ultrasound imaging, provided good "scar" volume quantification. When tested on 10 "scars" of different size and shape, PM resulted in lower bias (-9.7 vs 54.2 mm3) and narrower limits of agreement (-168.6 to 149.2 mm3 vs -296.0 to 404.4 mm3, P = .03). The interobserver variability for "scar" volume was better with PM (intraclass correlation coefficient = 0.901 vs 0.815). Two-dimensional and three-dimensional echocardiography with PM and SP was performed on 15 individuals with myocardial scar secondary to infarction. The CR was higher on PM imaging. Using cardiac magnetic resonance as a reference, quantification of myocardial scar volume showed better agreement when PM was used (bias, -645 mm3; limits of agreement, -3,158 to 1,868 mm3) as opposed to SP (bias, -1,138 mm3; limits of agreement, -5,510 to 3,233 mm3). CONCLUSIONS The PM modality increased the CR between tissues with different acoustic properties in an experimental in vitro "scar" model while allowing accurate quantification of "scar" volume. By applying the in vitro findings to humans, PM resulted in higher CR between scarred and healthy myocardium, providing better scar volume quantification than SP compared with cardiac magnetic resonance.

Abstract
Background: Right atrial pressure (RAP) can be estimated by echocardiography from inferior vena cava diameter and collapsibility (eRAPIVC), tricuspid E/e' ratio ( eRAP E / e ' ), or hepatic vein flow (eRAPHV). The mean of these estimates (eRAPmean) might be more accurate than single assessments. Methods and Results: eRAPIVC, eRAP E / e ' , eRAPHV (categorized in 5, 10, 15, or 20 mmHg), eRAPmean (continuous values) and invasive RAP (iRAP) were obtained in 43 consecutive patients undergoing right heart catheterization [median age 69 (58-75) years, 49% males]. There was a positive correlation between eRAPmean and iRAP (Spearman test r = 0.66, P < 0.001), with Bland-Altman test showing the best agreement for values <10 mmHg. There was also a trend for decreased concordance between eRAPIVC, eRAP E / e ' , eRAPHV, and iRAP across the 5- to 20-mmHg categories, and iRAP was significantly different from eRAP E / e ' and eRAPHV for the 20-mmHg category (Wilcoxon signed-rank test P = 0.02 and P < 0.001, respectively). The areas under the curve in predicting iRAP were nonsignificantly better for eRAPmean than for eRAPIVC at both 5-mmHg [0.64, 95% confidence interval (CI) 0.49-0.80 vs. 0.70, 95% CI 0.53-0.87; Wald test P = 0.41] and 10-mmHg (0.76, 95% CI 0.60-0.92 vs. 0.81, 95% CI 0.67-0.96; P = 0.43) thresholds. Conclusions: Our data suggest that multiparametric eRAPmean does not provide advantage over eRAPIVC, despite being more complex and time-consuming.

Abstract
The outbreak of coronavirus disease 2019 (COVID-19) in Italy, the first Western country hit by the pandemic, seriously impacted the Italian healthcare system and social and economic environment. This perspective piece focuses on the main challenges faced by Italian hospital managements: hospital overcrowding; the need for urgent reorganization of the country's healthcare systems; the lack of data regarding COVID-19 diagnostics, clinical course, and effective treatment; individual and collective consequences of the crisis; and the importance of disease containment measures and early treatment strategies.

Abstract
Atrial fibrillation is the most common arrhythmia in clinical practice. Although postoperative atrial fibrillation occurs in a small percentage of the total number of cases, it is associated with increased mortality, longer hospital stay and higher hospitalization costs, making this issue of particular relevance. The aim of this literature review is to describe the risk profile of this patient subset and to focus on the current knowledge of available prophylactic and therapeutic strategies.

Abstract
Several studies have been carried out on vulnerable plaque as the main culprit for ischaemic cardiac events. Historically, the most important diagnostic technique for studying coronary atherosclerotic disease was to determine the residual luminal diameter by angiographic measurement of the stenosis. However, it has become clear that vulnerable plaque rupture as well as thrombosis, rather than stenosis, triggers most acute ischaemic events and that the quantification of risk based merely on severity of the arterial stenosis is not sufficient. In the last decades, substantial progresses have been made on optimisation of techniques detecting the arterial wall morphology, plaque composition and inflammation. To date, the use of a single technique is not recommended to precisely identify the progression of the atherosclerotic process in human beings. In contrast, the integration of data that can be derived from multiple methods might improve our knowledge about plaque destabilisation. The aim of this narrative review is to update evidence on the accuracy of the currently available non-invasive and invasive imaging techniques in identifying components and morphologic characteristics associated with coronary plaque vulnerability.

Abstract
BACKGROUND The aim of this study was to evaluate differences in electrogastrographic activity and serum gastrin secretion in patients subjected to general anesthesia (GA) vs blended anesthesia (BA = GA plus epidural analgesia) for abdominal aortic surgery. METHODS Thirty-four patients (all males: 28 with abdominal aorta aneurysm, 6 with obstructive aorto-iliac disease; mean age: 68+/-7 years) were randomly assigned either to GA (N.=17) or to BA (N.=17) for abdominal aortic surgery. Each patient was evaluated for serum gastrin secretion at the time of electrogastrography (EGG) 24 h before and after surgery, using ambulatory equipment. Gastrin levels were tested under fasting conditions and after a standard meal. EGG shows gastric electrical activity that parallels gastric motor activity. RESULTS Before surgery, no significant difference was found for any of the EGG parameters or the serum gastrin integrated value (area under the curve [AUC]) between the two groups of patients. After surgery, an increased frequency of electrical waves (tachygastria) was observed in 22% of those undergoing GA and in 5% of patients undergoing BA. The power ratio (postprandial/fasting total power) was exceedingly high (>4) in 53% of the GA patients and in 11% of the BA patients (P<0.05). The gastrin AUC was 263+/-58 pg/mL in the GA group and 179+/-92 pg/mL in the BA group (P<0.01). CONCLUSIONS An excess of EGG activity and serum gastrin secretion was observed in patients undergoing GA vs those submitted to BA. Thus, the latter procedure seems to affect gastric function less than GA alone.

Abstract
BACKGROUND Diagnosis of pancreatic masses is often difficult. Endoscopic ultrasound-fine needle aspiration has been proposed as the best single-step strategy. AIMS To prospectively evaluate feasibility, effectiveness and safety of endoscopic ultrasound-fine needle aspiration of pancreatic masses in a consecutive study of unselected patients. METHODS Two hundred ninety-three patients were enrolled in two referral Hospitals in Northern Italy. All patients were referred either due to the presence of imaging test abnormalities (suspected or evident masses, or features indirectly suggesting the presence of a mass) or due to clinical or biochemical findings suggesting pancreatic cancer in the absence of positive imaging. All patients underwent linear array endoscopic ultrasound and, when indicated, fine needle aspiration. All procedures were recorded prospectively. The final diagnosis was established at the end of follow-up or when the patients underwent surgery or died. RESULTS Fine needle aspiration was indicated in 246 of 293 cases (84%), considered technically feasible in 232 of 246 cases (94%) and gave adequate samples for histopathological diagnosis in 204 of 232 cases (88%). Endoscopic ultrasound sensitivity, specificity and accuracy were 79, 60 and 72%, respectively; the corresponding figures for endoscopic ultrasound-fine needle aspiration were 80, 86 and 82%. There was good agreement with final diagnosis for endoscopic ultrasound-fine needle aspiration (kappa 0.673, 95%CI 0.592-0.753), greater than that for endoscopic ultrasound alone (kappa 0.515, 95%CI 0.425-0.605). There was one case of intracystic haemorrhage and one case of transient hyperthermia (0.3%). CONCLUSIONS Endoscopic ultrasound-fine needle aspiration of pancreatic masses seems to be feasible, effective and safe in this consecutive study of patients.

Abstract
The effect of the stearoyl-CoA desaturase (SCD) gene on milk fatty acid composition was tested. Cows of 3 breeds of northern Italy, Piedmontese, Valdostana, and Jersey, were genotyped at exon 5 of the SCD gene. This has been suggested as a primary candidate gene to change the proportion of saturated vs. unsaturated fatty acids in milk, wherein a single nucleotide polymorphism (C/T) gives rise to a different AA codon. It was possible to ascribe a reduced desaturase activity to the T allele only in the case of caproleic and myristoleic fatty acids. In contrast with the findings of SCD effects on carcass fat, it was not possible to confirm the higher desaturation activity of this single nucleotide polymorphism on long-chain fatty acids, due to the different pathways that originate milk fatty acids of different carbon length; long-chain fatty acids are highly influenced by the complex metabolic events that affect the ingested nutrients during their transfer to milk fat.

Abstract
BACKGROUND Major limitations of endoscopic retrograde cholangiopancreatography in paediatric populations are a low incidence of biliopancreatic disease among children, the equipment dimensions (size of endoscopes and devices) and the increasing role of MR-cholangiopancreatography in the field of diagnostic indications. Aim of this study was to evaluate the diagnostic and therapeutic yields of endoscopic retrograde cholangiopancreatography for biliopancreatic diseases in a paediatric population. METHODS Between 1996 and 2002, 48 endoscopic retrograde cholangiopancreatographies were performed in 38 children aged 4 weeks to 17 years as part of the diagnostic evaluation for suspected pancreatic or biliary tract disease. Endoscopic retrograde cholangiopancreatography was carried out under general anaesthesia, using prototype paediatric duodenoscopes or standard duodenoscopes in children younger or older than 18 months, respectively. RESULTS The indications to perform endoscopic retrograde cholangiopancreatography were common bile duct stones (14 children), biliopancreatic abnormalities (8), primary sclerosing cholangitis (2), Wirsung disruption (1), biliary leakage (1), cholestasis (4) and pancreatitis (8). Cannulation was successful in all patients but one. Sphincterotomy together with stone extraction or stent insertion was performed in 30/38 patients. Immediate complications were mild and treated conservatively. CONCLUSIONS Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography can be used safely and effectively in the management of biliopancreatic diseases in childhood as well. Indications, endoscopic techniques and complications are similar to those reported for adult patients.

Abstract
Relationships among plasma hormonal and metabolic variables in the last trimester of gestation in 59 Piedmontese dams (n = 15 heifers, n = 44 cows) and the calf birth weight (BWT) class of their offspring were investigated in seven herds. The BWT data were categorized as follows: > 50 kg (BWT-A), 46 to 50 kg (BWT-B), 41 to 45 kg (BWT-C), and < 41 kg (BWT-D). Blood samples were collected at 33, 36, and 39 wk of gestation. Packed cell volume (PCV) and plasma concentrations of insulin, estrone sulfate (E1SO4), NEFA, and creatinine were determined and correlated to BWT class. Creatinine: E1SO4 ratio also was calculated. Duration of gestation was greater for dams producing a BWT-A calf than for the other BWT classes, and calf BWT was heavier (P < 0.001) for calves in the BWT-A vs. BWT-D class. The heaviest calf in BWT-A was associated with the highest calving difficulty score. Insulin and PCV values were not affected by week of gestation, whereas plasma E1SO4, NEFA, and creatinine content increased (P < 0.001) and creatinine:E1SO4 decreased (P < 0.001) during late gestation. Calf BWT class did not affect PCV value. Plasma E1SO4 concentrations were lower (P < 0.01) in BWT-D dams than the other dams, showing the greatest difference at 39 wk of gestation. At 36 and 39 wk of gestation, dams bearing BWT-C and BWT-D calves had a higher (P < 0.01) plasma insulin concentration than those bearing BWT-A and BWT-B calves. Plasma NEFA concentrations at 39 wk of gestation were higher (P < 0.05) in dams of calf BWT-A than in the other dams. We conclude that plasma E1SO4 level is a variable that can be used to monitor problems related to a small size calf. Conversely, the forthcoming birth of a calf with a heavy BW seems to be preceded by a pronounced increase in plasma NEFA level in the dam just a few days before calving.

Abstract
AIM Partial gastrectomy and Helicobacter pylori (H. pylori) infection are considered 2 risk factors for gastric cancer development. False negative urea breath test (UBT) results have been described in patients with gastric surgery, due to rapid gastric emptying of urea solution from the stomach. On the other hand, a rapid 10-minute 14C-UBT proved to be highly reliable for diagnosis of H. pylori infection when delaying test meal was omitted. Aim of this study was to improve the diagnostic accuracy of 13C-UBT in patients with gastric resection. METHODS UBT was performed in 100 gastrectomised patients with breath collection at 0, 10, 15, 20, 25 and 30 minutes (multi-UBT) after 100 mg 13C urea ingestion and 100 ml of marketed fruit juice. In 28 cases contemporary histological data from biopsy specimens (within 1 month, in absence of treatment) were also available. RESULTS Multi-UBT was persistently negative or positive in all the samplings in 34% and 25% of cases, respectively. Positivity only at 30 minutes was found in 10% of cases, while 19% of subjects were positive at 15-25 minutes but not at 30 minutes. In 12% of cases the test was positive only at 10 minutes. CONCLUSIONS Multi-UBT offers a not negligible diagnostic improvement over the standard UBT: at least 19%, and up to 31% if positivity at ''10-minute only'' is taken into account. This method can be useful when accurate diagnosis of H. pylori infection is required in gastrectomised patients.

Abstract
AIM To evaluate the choice and relative effectiveness of Helicobacter pylori eradication regimens in a primary care setting. PATIENTS AND METHODS Patients referred to our department, who had been treated for H. pylori infection during the preceding 6 months, were enrolled between September 1998 and July 1999. H. pylori status was assessed by urea breath test. Information on the drugs administered, compliance and side-effects was recorded. RESULTS The mean eradication rate was 72% in patients receiving their first course of treatment (1863 cases; 45% male; mean age, 53 +/- 14 years); a double therapy regimen was prescribed to 14% of patients, triple therapy to 85% and quadruple therapy to 1%. Maastricht Consensus proton pump inhibitor-based regimens were prescribed in 80% of cases, with a mean eradication rate of 73%. No statistically significant correlation was found between eradication failure and sex, age, endoscopic findings or administered treatment. CONCLUSIONS In Italy, in a primary care setting, first-line H. pylori eradication therapies reflect international guidelines. The efficacy of such regimens is lower than that reported by controlled trials. These results are relevant when making pharmacoeconomic evaluations of H. pylori management.

H. pylori status was assessed by urea breath test and recorded together with information about administered drugs, compliance, side effects. RESULTS In patients undergone the first treatment course (1863 cases, 45% M, mean age 53+/-14 yrs) the mean eradication rate (ER) was 72%: a double therapy was prescribed in 14% of cases, a triple therapy in 85% and a quadruple in 1%. Maastricht Consensus PPI-based regimens were prescribed in 80% of total cases with a mean ER of 73%. No statistical significant correlation was found between eradication failure and sex, age or administered treatment. CONCLUSIONS In Italy, in primary care setting: 1) first line H. pylori eradication therapies reflect international guidelines; 2) the efficacy of such regimens is lower than the one reported by controlled trials: such data should be kept in mind when pharmacoeconomic evaluations of H. pylori management are drawn.

BACKGROUND Aim of the present study was to evaluate the use of UBT in a primary care setting. METHODS From September 1998 to July 1999 we studied 2810 consecutive patients, referred to the Department of Gastroenterology, Mauriziano Hospital, Torino. A structured questionnaire was used to record information on demographic characteristics and clinical history. 13C-UBT was performed by means of isotope ratio mass spectrometer. RESULTS The results shown that: 1) the main indication to perform UBT was the evaluation of treatment success (72% of cases); 2) in patients aged less than 45 years and never assessed before for H. pylori infection, UBT was used as first line procedure in 68% of cases: this finding stand for an initial adoption of the ''test and treat'' strategy; 3) first line H. pylori eradication therapies reflect international guidelines. CONCLUSIONS The effectiveness of therapeutic regimens results to be decreased when translated into routine clinical practice.

A prognostic role for serology has also been hypothesised. AIMS To evaluate anti-Saccharomyces cerevisiae antibody distribution in an unselected Italian inflammatory bowel disease population. To analyse whether anti-Saccharomyces cerevisiae antibody status (positive/negative) and/or anti-Saccharomyces cerevisiae antibody titres are associated with clinical variables and outcome measures in Crohn's disease patients. PATIENTS AND METHODS A series of 299 inflammatory bowel disease patients were evaluated; serum samples were taken and a short clinical history was recorded. anti-Saccharomyces cerevisiae antibodies IgG enzyme-linked immunosorbent assay Medilab (Milan, Italy) kit was used in order to determine anti-Saccharomyces cerevisiae antibody status. RESULTS Sensitivity, specificity and likelihood ratio for positive test in the differential diagnosis of inflammatory bowel disease was 59%, 89%, 8.1, respectively. Clinical variables significantly associated with anti-Saccharomyces cerevisiae antibody status in logistic regression were found to be ileal location (p=0.01) and earlier age at diagnosis (p<0.01). Among ileal Crohn's disease patients, there was a trend in concordance between anti-Saccharomyces cerevisiae antibody titres and higher number of surgical procedures which was not statistically significant applying more complex statistics. CONCLUSIONS In an Italian inflammatory bowel disease population, anti-Saccharomyces cerevisiae antibodies status showed characteristics similar to those previously reported. Anti-Saccharomyces cerevisiae antibody positivity is associated with ileal involvement and with earlier onset of Crohn's disease.

Abstract
BACKGROUND Quantitative determination of pancreatic elastase-1 (E1) in stools has been proposed as a novel, noninvasive test of pancreatic function. The aim of the study was to verify its role in the differential diagnosis of chronic diarrhea. METHODS E1 was measured in spot stool samples of 50 patients with pancreatic disease (PD), 62 with inflammatory bowel disease (IBD), 45 with chronic diarrhea (CD), 34 with other gastroduodenal and liver disease (gastrointestinal; GI), and in 18 normal controls, by a commercial kit (Schebo-Tech., Wettemburg, Germany). RESULTS In PD, patients with severe damage and diarrhea displayed E1 levels below 100 microg/g; normal values were found in mild-moderate disease. Abnormal values were detected in 4 CD and in 14 IBD patients, either in the presence of severe protein malnutrition or in patients with previous ileo-anal pouch anastomosis and pouchitis. In nine cases, values reverted to normal after adequate treatment. Diagnostic accuracy of E1 in discriminating diarrhea of pancreatic and nonpancreatic origin was: SS, 97%; SP, 84%; VP+, 66%; VP-, 100%. CONCLUSION 1) The finding of a normal E1 value rules out a malabsorption of pancreatic origin. 2) in CD and IBD, decreased E1 might be owing to bacterial elastase degradation (pouchitis) or transient defective pancreatic enzyme secretion.

Abstract
BACKGROUND Little information is available on the pathogenesis of cholesterol microlithiasis, and it is not clear if biliary lipid composition in these patients is similar to changes seen in cholesterol gall stone patients. AIMS To measure biliary lipid composition in patients with cholesterol microlithiasis. PATIENTS Eleven patients with cholesterol microlithiasis, 20 cholesterol gall stone patients, and 17 healthy controls. METHODS Duodenal bile was collected in the fasting state during ceruletide infusion. Biliary cholesterol, phospholipids, and total bile acids were analysed by enzymatic assays, and conjugated bile acids by high pressure liquid chromatography. RESULTS Patients with microlithiasis had a cholesterol saturation index significantly higher than controls (mean value 1.30 (95% confidence interval 1.05-1.54) v 0.90 (0.72-1.08)) but similar to gall stone patients (1.51 (1.40-1.63)). This was due to a significant decrease in per cent phospholipid (10.0% (7.1-12.8)) compared with controls (21.4% (18.1-24.6)) and gall stone patients (24.9% (20.5-29.3)). Per cent cholesterol was similar in patients with microlithiasis and controls (5.3% (4.5-6.1) and 5.6 % (4.3-6.8), respectively) but was significantly increased in gall stone patients (10.9% (9.3-12.4)). Bile acid composition in patients with microlithiasis was similar to controls whereas in gall stone patients deoxycholic acid was significantly increased: 27.3% (24.8-29.7) v 19.0% (15.7-22.2) in controls and 20.6% (14.9-26.2) in patients with microlithiasis. CONCLUSION Patients with cholesterol microlithiasis have biliary cholesterol supersaturation, similarly to cholesterol gall stone patients. Whereas in the latter this is due to increased per cent cholesterol, in patients with microlithiasis this is caused by phospholipid deficiency, with normal per cent cholesterol and normal biliary bile acid composition.

Abstract
BACKGROUND AND AIM A high prevalence of Helicobacter pylori (Hp) infection in diabetic patients has been described in recent years. This study investigates its prevalence in type 2 diabetics and its correlation with the degree of metabolic control and the presence of chronic complications. METHODS AND RESULTS Forty-one consecutive type 2 diabetics (21 males, 20 females aged 46-78, mean 62) and 31 age-matched controls participated. Hp infection was assessed by means of the 13C-urea breath test. Fasting glucose and glycated haemoglobin (HbA1c) levels were measured to evaluate metabolic control. Chronic complications were assessed by means of albumin excretion rate (AER), fundoscopy, vibratory perception threshold (VPT), ECG, clinical history of coronary, cerebral or peripheral arteriopathy, foot examination and cardiovascular autonomic function tests. A higher prevalence of Hp infection was found in diabetic than in control women (80% vs 37.5%; p < 0.05), whereas there was no difference between males. A higher prevalence correlated with macroangiopathy and neuropathy and higher BMI, blood pressure, fasting glucose and HbA1c values. By contrast, microangiopathy was significantly more prevalent (p < 0.05) in Hp negative (85%) than in Hp positive patients (48%). CONCLUSIONS There is a high prevalence of Hp infection in type 2 diabetic women. The absence of microangiopathy may be a predisposing factor: microvascular changes in the gastric mucosa may create an unfavourable environment for the establishment or survival of Hp.

Abstract
BACKGROUND The reference diagnostic methods available for detection of Helicobacter pylori infection are either invasive (histology) or expensive and highly sophisticated (Urea Breath Test). A new enzyme immunoassay, which can be easily performed in any laboratory, has been developed to detect Helicobacter pylori in stool specimens (HpSA-Meridian Diagnostics, Cincinnati, USA). Aim of the study was to compare HpSA to Urea Breath Test. PATIENTS AND METHODS A total of 125 patients (52 never treated for Helicobacter pylori infection and 73 after Helicobacter pylori eradication therapy) referring to our Department, underwent both tests within two weeks. RESULTS Contrasting results between the two tests were found in 30% of cases: in 19% of the untreated patients and in 37% of the treated patients (p<0.001). The main discrepancy consisted in positive HpSA associated with negative Urea Breath Test. Mean HpSA value in such conditions was 0.273 optical density, while in patients with both positive tests, it was 1.192 optical density. In untreated, but not in treated patients, raising the HpSA cut off value significantly decreased the percentage of conflicting results. CONCLUSIONS Some disagreement was detected between HpSA and Urea Breath Test results, especially in treated patients. Possible explanations for our findings are a low HpSA cut off value together with the identification of Helicobacter pylori coccoid forms by the immunoassay but not by the urease based Urea Breath Test. The higher percentage of discrepancy detected in treated patients might support this hypothesis.

Abstract
Increased levels of pancreatic enzymes have been reported in patients with renal insufficiency and ascribed either to impaired urinary excretion or, in a few studies, to the presence of pancreatic damage. In the present study serum total amylase, pancreatic amylase, and lipase were evaluated in 63 patients with chronic renal insufficiency (CRF), in 98 patients on hemodialysis (HD), in 28 patients on continuous ambulatory peritoneal dialysis (CAPD), in 23 patients with renal transplantation (RT), and in 34 normal volunteers (C). Serum parathyroid hormone and triglyceride levels were also measured in the majority of patients. Ultrasound examination of the pancreas was performed in a select number of cases. Mean values of pancreatic enzymes were significantly higher in all the study groups in comparison with controls, but values exceeding three times the upper normal limit were detected only in HD patients, who also showed amylase and lipase levels significantly highly than those of CAPD and CRF subjects. Negligible amounts of pancreatic enzymes were detected in peritoneal fluid of CAPD patients. Significant correlations were found with serum creatinine in CRF, with parathyroid hormone in HD and CAPD, and with duration of treatment in HD. No pancreatic abnormalities were detected by ultrasound. In conclusion, very high levels of pancreatic enzymes are seen mainly in HD patients and might be related more to the metabolic derangement of long-term dialysis treatment than to the occurrence of acute pancreatic damage.

Abstract
We evaluated the circadian pattern of gastric acidity by prolonged intraluminal pHmetry in 15 "responder" and 10 "nonresponder" duodenal ulcer patients after nocturnal administration of placebo, ranitidine, and famotidine. Acidity was measured during predefined periods under the different drug regimens in the two groups of subjects, and a comparison was performed both within and between groups. With placebo, significantly lower median 24-h pH values were detected in patients with resistant ulcer than in responders (1.13 versus 1.63). On the contrary, no statistical difference was detected between the two groups during any time of day after administration of either ranitidine or famotidine. Within each group, no significant difference was noted between the two different H2-blockers. Thus, our data suggest that patients with resistant duodenal ulcer display an increased gastric acidity in control conditions but a "normal" response to administration of antisecretory drugs.

Abstract
Gastric pH was monitored, by means of a computerized system, in healthy controls (C) and in patients with active duodenal ulcer (ADU) and inactive duodenal ulcer (IDU). The test was performed before treatment and during administration of a single dose of ranitidine 150 mg, cimetidine 400 mg, and pirenzepine 50 mg, in random sequence at 12-h intervals, (10 am, 10 pm). Under basal conditions, progressively lower median pH values were detected in ADU and IDU patients, compared with controls. A significant difference was found between C and ADU during daytime (1.38 vs. 0.85), nighttime (1.29 vs. 0.81), and 24 h (1.35 vs. 0.81) and between C and IDU during 24 h (1.35 vs. 1.11). However, no statistical difference was observed between patients with active and inactive ulcer disease. Administration of ranitidine and cimetidine significantly increased gastric pH during nighttime but not during daytime. Ranitidine, at the doses studied, proved to be more potent than cimetidine in suppressing gastric acidity. Gastric pH was unaffected by pirenzepine in most cases.

Abstract
Ultrasonic monitoring of the pancreas following secretin stimulation has shown to cause a marked dilatation of Wirsung duct; whether this phenomenon is due to the stimulation of pancreatic secretion and/or to the effect of secretin on the sphincter of Oddi (SO) motility is unknown. In the present study pancreatic scan after secretin was performed in 11 patients with nonpancreatic diseases after premedication with glucagon (inhibition of both pancreatic secretion and SO motility) or tyropramide (inhibition of SO motor function) and in patients with different degrees of pancreatic insufficiency. Serum immunoreactive trypsinogen (IRT) levels were measured in all the subjects during the test. Premedication with glucagon completely abolished both Wirsung enlargement and serum IRT increase, while tyropramide significantly reduced, but did not abolish, the response to secretin. These results suggest that both stimulation of pancreatic secretion and the increase of SO pressure are prerequisites for a full-blown occurrence of the secretin-induced modifications of Wirsung. Within chronic pancreatitis patients, the response to secretin was exaggerated in those with a still preserved pancreatic function and it was lacking in those with severe pancreatic insufficiency.

Abstract
We evaluated long-term treatment with either ranitidine (R) or sucralfate (S) in the prevention of duodenal ulcer recurrences. Fifty-nine patients with healed ulcers were randomly allocated to maintenance treatment with 150 mg R nightly or 2 g/day S. By using a life table analysis, the calculated probable remission rates at 4, 8, and 12 months were 90, 85, and 53% with R, respectively, and 62, 62, and 53% with S, respectively. These differences were not significant at any interval. In both groups ulcer relapse was independent of sex, smoking habit, and alcohol and coffee consumption, whereas a history longer than 5 years was significantly related to a higher probability of recurrence. No relevant clinical or biochemical side effects were encountered with either drug, but compliance rate was higher in the R group. R and S are equally effective in preventing duodenal ulcer relapse over a 1-year period of maintenance treatment, although R proved to be more effective in preventing early relapse.

Abstract
The levels of serum immunoreactive trypsinogen and P-isoamylase in response to Bombesin intravenous infusion were evaluated in 25 controls, 18 patients with documented chronic pancreatitis, and nine subjects with nonpancreatic gastroenterological diseases. Mean immunoreactive trypsinogen peak values were significantly higher in controls and gastroenterological diseases than in chronic pancreatitis, but there was marked overlap in individual values between the three groups. As for P-isoamylase, a statistical difference was detected only between mean peak concentrations of control versus chronic pancreatitis. Integrated responses for both enzymes did not result in a better discrimination between controls, chronic pancreatitis, and gastroenterological diseases. This study confirms that evocative tests are of limited value in the diagnosis of pancreatic disease.

Abstract
Levels of a new carbohydrate antigen CA 19-9, which is a monosialoganglioside identified by a monoclonal antibody raised against colorectal carcinoma cells, were compared to carcinoembryonic antigen and tissue polypeptide antigen assays in 250 sera from patients with different pancreatic diseases including acute pancreatitis, chronic pancreatitis, and pancreatic cancer. All three tumoral markers were elevated at the onset of an acute pancreatic attack in a few patients. All but five patients with chronic pancreatitis displayed normal levels with each of the three markers; in two of these five cases an extraintestinal cancer was later discovered. CA 19-9 displayed higher sensitivity and predictive value of a negative result than the other two markers. The best operational characteristic of CA 19-9 was its high predictive value for a positive test which suggests a "ruling in" usage of it for pancreatic cancer diagnosis. CA 19-9 assay was of extreme value in disclosing both localized and metastatic pancreatic cancer while the other two markers were more often positive in the latter case. Of 71 cancer patients with positive markers, only four would have escaped a right diagnosis by assaying CA 19-9 alone.

Abstract
A computer-assisted technique for prolonged gastric pH monitoring has been developed using a personal computer. Segments of signal from several studies performed in controls and on patients with duodenal ulcers were chosen for comparison between manual and digital pH readings; no significant difference was detected. In clinical practice this system might provide an additional tool in the diagnostic and therapeutic treatment of peptic ulcer disease.
